Auriel: Plant & Light Meter

Never kill a plant again.

Auriel is the plant app that measures your actual light — so its recommendations are honest, not generic. Point it at any window to score the light. Get a library of 300+ plants filtered to what will actually thrive in your real home.

• Identify 1,000+ plants in seconds using on-device AI — no account, works offline.
• 300+ plant library with real photos, light requirements, care schedules, and troubleshooting.
• Measure any window with your iPhone camera. Get a 0–100 Sun Score plus a letter grade calibrated to household reality.
• Scan a garden bed to get a DLI (Daily Light Integral) value and a shade compass showing which direction your shade is coming from.
• Matched plants for every spot — filtered by difficulty, water need, pet-safe status, and 10 curated collections (Low-Light Survivors, Native Pollinators, Kitchen Herbs, and more).
• Seasonal planting calendar that knows your hemisphere and climate.
• Beautiful year-round sun-path heatmap for any location.
• Golden hour notifications that respect your actual home.
• Full light + dark theme, with a warm cream light mode.
Auriel is 100% private by design:
